UNSPSC 12140000: Elements and gases

UNSPSC 12140000 Elements and gases (Family) encompasses specialty and industrial gas supply, calibration gases, laboratory consumables, and related services that state and local governments procure to support operations at water treatment plants, wastewater facilities, environmental monitoring stations, fleet maintenance shops, educational welding programs, forensic laboratories, and medical gas infrastructure. Recent solicitations show state and local buyers sourcing EPA Protocol calibration and audit gases for continuous emissions monitoring compliance, laboratory gas supplies for water quality analysis, welding gases and consumables for vocational education and fabrication work, medical gas systems inspection and certification, specialty chemicals for phosphate removal and water treatment, and miscellaneous shop supplies including oils, lubricants, and cleaning agents for fleet and facility maintenance.

Issuing bodies across the code span county transportation authorities, municipal water and wastewater authorities, city public works departments, community colleges, school districts, county forensic institutes, and special-purpose water authorities. The Orange County Transportation Authority appears twice in recent postings (IFBs 250325 and 250457, both for miscellaneous auto and shop supplies), and the City of Tucson has posted multiple procurements spanning MRO supplies, machine shop services, and calibration gases. Geographic concentration is moderate across the United States, with recent activity centered in California (Orange County, City of Tucson, Mt. San Antonio Community College, City of Milpitas), Texas (Harris County Institute of Forensic Science, Collin College, Texas A&M University), Pennsylvania (Berks-Montgomery Municipal Authority, Morrisville Municipal Authority), Florida (Tampa Bay Water, City of Palm Bay, Marion County), and Oregon (Mt. Hood Community College, City of Salem). Representative recent opportunities include the County of Orange's IFB 0803068001RE for EPA Protocol calibration and audit gases (due August 10, 2026) with a five-year usage agreement and firm fixed pricing, the Orange County Transportation Authority's IFB 250457 for miscellaneous auto and shop supplies (due September 1, 2026) at $500,000 over two years, and the City of Tucson's RFP 240078 for comprehensive MRO supplies with cooperative purchasing through OMNIA Partners (due March 28, 2024, but reflecting recent posting). A notable canceled Illinois state solicitation (B-53314 for argon, helium, and nitrogen) signals procurement volatility at the state level; most current activity remains concentrated in municipal and regional utility procurement.
